1 Claim. (Cl. 20-101) This invention relates to building constructions, and more particularly to an improved insulating block, and a process of forming same, from aluminum-coated, inorganic granular material which is pumped between the studs of a building wall.

One object of the present invention is to provide an insulating block of the above nature in which the granular particles of the block are separated from each other by air spaces so as to render the block porous for ventilating purposes and to prevent the accumulation of moisture within the building wall.

A further object is to'provide an insulating wall block of the above nature, which will be simple in construction, inexpensive to manufacture, easy to install and manipulate, compact, and very eificient and durable in use.

With these and other objects in view there has been illustrated on the accompanying drawing, one form in which the invention may conveniently be embodied in practice.

In the drawing,

Fig. 1 represents a fragmentary side view of a building wall in which the improved insulating block has been installed between a pair of vertical studs by pumping it in loose from the top of the wall, the interior wall board being shown in dotted lines.

Fig. 2 is a fragmentary side view of the same with the wall board shown in full lines.

Fig. 3 is a perspective view of a portion of the compacted granular insulating block shown by itself, said block being self-supporting so that it will not exert pressure on the side walls of the building.

Fig. 4 shows a magnified corner of block 15.

Referring now to the drawing in which like reference numerals denote corresponding parts throughout the several views, the numeral indicates a plurality of clapboards located on the outside of a building, said clapboards being surmounted by a top plate 11 and being located above a bottom sill 12, at the foundation of the building.

The usual vertically spaced 2 x 4" studs mounted on 16" centers, are indicated by the numeral 13, and according to the present invention a sufficient quantity of grains 14 of inorganic material, such as washed sand, coated with sticky adhesive aluminum paint will be pumped into the top of the building Wall in loose condition between the studs 13 from a' pipe 16 as clearly shown in Fig. 1.

After the grains 14 have filled the space between the studs, they will be compacted slightly into the form of a porous solid block 15, as clearly shown in Fig. 3.

Operation The first step in the operation of applieants process ice of insulating a wall of a building is to tumble washed sand or other inorganic material in a rotating barrel, with aluminum paint, japan dryer or other adhesive. The inorganic material may be fine, coarse or medium, but must be free from silt, which might obstruct the ventilation and permit the accumulation of moisture by condensation.

The second step of the process after the aluminum paint coated material has become completely dry, is to again tumble said material in the barrel to apply a second coat of aluminum paint thereto.

The third step of the process is to pump the material while still sticky into the top of and between the pair of spaced 2 X 4 studs 13. The sticky paint on the eX- terior of the grains 14 will cause them to adhere together into porous block form so that there will be no side pressure on the walls which might cause damage thereto. If desired, a slight pressure may be exerted on the top of the block 15 of the granular aluminum paint coated material so as to cause the grains thereof to become compacted and adhere more tightly together.

The advantages of the improved insulating block are that it will be heat and cold insulating due to the reflecting qualities of the aluminum paint and the dead air spaces between the grains. It will also be fireproof, soundproof, a non-conductor of electricity, non-sweating, and insect and termite proof. It will also have sufficient weight, (about lbs. per cubic foot) to hold the building on its foundation, making it resistant to the effects of high winds or tornadoes. The present improved insulating block may be used hold as well as new houses and constitutes an inexpensive method of insulating such buildings.

While there has been disclosed in this specification, one form in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, and that the invention is not limited to the specific disclosure but may be modified and embodied in various other equivalent forms without departing from its spirit. In short, the invention includes all the modifications and embodiments coming within the scope of the following claim.

Having thus fully described the invention what is claimed as new and for which it is desired to secure Letters Patent is:

The process of insulating the wall of a building, which comprises pumping into the space between a pair of vertical studs of said wall, a quantity of sand granules which have been impregnated with aluminum paint which has then been allowed to dry, said granules also having an exterior coating of sticky aluminum paint to cause said sand granules to adhere to each other while in place within said wall, and then applying a slight pressure to said mass of sticky sand granules to produce a compact porous heat-and-cold insulating, fireproof, soundproof, non-sweating block which will be self-supporting and which will not exert any substantial pressure against the sides of said wall.
